This paper appraises the work of Harry Braverman (1920–76), specifically his classic, Labor and Monopoly Capital, published in 1974 and remaining an influential reference for what has become the labour process approach to the study of work in capitalist societies. Labor and Monopoly Capital (LMC) reshaped what was then known as industrial sociology in the English-speaking world and was impactful across a range of disciplines, including history, organisation and management studies, comparative political economy, and labour geography. It is widely regarded as the foundational text of labour process theory (LPT). Fifty years after the initial publication of LMC, that theoretical approach is not only alive and well, but in the past decade, undergone something of a resurgence, influencing global communities of scholars. The paper takes a close look primarily at the text in its context, examining the genesis of the arguments, the distinctive biography of the author, and the structure of the book drawing out its major and minor themes, including a critical assessment of sources and evidence. We argue that the enormous impact of LMC can be explained by its successful challenge to existing orthodoxies about trajectories in work, technology, and management dominant in the social sciences and orthodox Marxism. This is followed up with a discussion of the reception, diffusion, and development of LMC comparatively and across different geographic domains and academic disciplines. As the debate on LMC eventually became a much broader programme of theory and research on the labour process, we consider some of the key points of differentiation from one of the foundational texts. Whilst acknowledging its enduring legacy, the final section argues that there is only a route forward from, rather than back to Braverman, given the profound changes to global capital and labour in the 50 years since LMC appeared.
